As a dog owner, you’re likely aware of the importance of your furry friend’s dental health. Dogs use their teeth not only for eating but also for a variety of activities like playing, grooming, and defending themselves. Understanding how many teeth dogs have and their dental structure can help you maintain their oral health and overall well-being. In this comprehensive guide, we’ll explore the fascinating world of canine dentition by explaining how many teeth do dogs have.

The Basics of Dog Dental Anatomy

Dogs, like humans, have two sets of teeth during their lifetime: deciduous (baby) teeth and permanent (adult) teeth. Let’s delve into the specifics:

1. Deciduous Teeth

Puppies are born without teeth, but deciduous teeth begin to emerge at around three weeks of age.
By the time a puppy reaches six months, they typically have a full set of 28 deciduous teeth.
These baby teeth are essential for chewing, playing, and exploring but are eventually replaced by permanent teeth.

2. Permanent Teeth

Dogs have a total of 42 permanent teeth, which replace the deciduous teeth.
The permanent teeth consist of the incisors, canines, premolars, and molars, which serve various functions in biting, tearing, and grinding food.
The dental formula for adult dogs is: 2(I 3/3, C 1/1, P 4/4, M 2/3) = 42 teeth.

Now, let’s break down the types of teeth and their roles:

Incisors (I)

These are the small, flat teeth located in the front of the mouth. Dogs have six upper and six lower incisors. Incisors are primarily used for grasping and nibbling food.

Canines (C)

The canines are the sharp, pointed teeth located on either side of the incisors. Dogs have four canines, two on the top and two on the bottom. These teeth are designed for gripping and tearing food and can also serve as a weapon when needed.

Premolars (P)

Premolars are located behind the canines and come in four pairs, making a total of eight premolars in a dog’s mouth. These teeth are responsible for tearing, shearing, and crushing food.

Molars (M)

Molars are the large, flat teeth found at the back of the mouth. Adult dogs have ten molars. They are crucial for grinding and crushing food, aiding in the digestive process.

Dental Care for Dogs

Maintaining your dog’s dental health is vital to their overall well-being. Poor dental hygiene can lead to dental diseases, which can have systemic effects on your pet’s health. Here are some tips for keeping your dog’s teeth clean and healthy:

1. Regular Brushing

Just as you brush your teeth daily, make an effort to brush your dog’s teeth regularly using a pet-friendly toothbrush and toothpaste. Start this habit early in your dog’s life to make it more comfortable for both of you.

2. Dental Chews and Toys

Consider offering dental chews and toys designed to help remove plaque and tartar. These can be both enjoyable and beneficial for your dog’s oral health.

3. Professional Cleanings

Schedule regular dental check-ups with your veterinarian. They can perform professional cleanings and address any dental issues promptly.

4. Balanced Diet

Feeding your dog a balanced diet that supports dental health can make a difference. There are specialized dental diets available that can help reduce plaque and tartar buildup.

5. Dental Water Additives

Some pet owners find dental water additives helpful in reducing plaque and freshening their dog’s breath.

Common Dental Issues in Dogs

Now that we have a better understanding of canine dentition and the importance of dental care let’s explore some common dental issues that can affect dogs:

1. Dental Plaque and Tartar

Plaque is a sticky film of bacteria that forms on the teeth. If not removed through brushing or chewing, it can harden into tartar (also called calculus). Tartar buildup can lead to gum inflammation and dental disease.

2. Gingivitis

Gingivitis is inflammation of the gums. It is often the result of plaque and tartar accumulation at the gum line. Signs of gingivitis include red, swollen gums and bad breath.

3. Periodontal Disease

This is a more advanced stage of dental disease that affects the supporting structures of the teeth, including the ligaments and bones. Periodontal disease can lead to tooth mobility and loss if left untreated.

4. Tooth Decay

While not as common in dogs as in humans, tooth decay can still occur. It is often seen in dogs that consume a high-sugar diet.

5. Broken or Fractured Teeth

Dogs are known for their powerful jaws, but their teeth can still break or fracture, especially when chewing on hard objects like bones or rocks. Broken teeth can be painful and may require dental treatment.

6. Tooth Abscess

An abscess is a pocket of infection that can develop when bacteria invade the tooth’s pulp. It is a painful condition that may require tooth extraction or root canal therapy.

7. Malocclusion

Malocclusion refers to misalignment of the teeth or jaws. This condition can lead to issues with biting and chewing and may require orthodontic treatment.

8. Oral Tumors

While less common, oral tumors can develop in dogs. Regular dental check-ups can help detect these issues early for timely intervention.

Signs of Dental Problems in Dogs

Recognizing the signs of dental problems in dogs is essential for early intervention and treatment. Watch out for the following indicators:

1. Bad breath

Persistent bad breath, also known as halitosis, is often an early sign of dental disease.

2. Drooling

Excessive drooling, especially if it’s a new or unusual behavior, can be a sign of dental discomfort.

3. Pawing at the mouth

Dogs in pain may paw at their mouths or face.

4. Loss of appetite

Dental problems can make eating painful, leading to a decreased appetite.

5. Visible tartar or discolored teeth

Inspect your dog’s teeth regularly for any signs of tartar buildup, discoloration, or damage.

6. Behavioral changes

Pain from dental issues can lead to changes in behavior, such as aggression or withdrawal.


Understanding how many teeth dogs have and their dental anatomy is the first step in ensuring your canine companion’s oral health. Regular dental care, including brushing, dental chews, professional cleanings, and a balanced diet, can go a long way in preventing dental issues. Keep a close eye on your dog’s oral health, and if you notice any signs of dental problems, consult your veterinarian promptly. With proper care, you can help your furry friend maintain a healthy and happy smile throughout their life.
